Inheritance diagram for Rndm::DefinedPdf:


The probability distribution function (Pdf) must be provided by the user as an array of positive real number. The array size must also be provided. The Pdf doesn't need to be normalized to 1. if IntType = 0 ( default value ) a uniform random number is generated. The uniform number is then transformed to the user's distribution using the cumulative probability distribution constructed from his histogram. The cumulative distribution is inverted using a binary search for the nearest bin boundary and a linear interpolation within the bin. Therefore a constant density within each bin is generated. if IntType = 1 no interpolation is performed and the result is a discrete distribution.
